Example: How to run Request B only if Request A returns status 200?

In Request A's Tests tab, write:<br>

if (pm.response.code === 200) {
  postman.setNextRequest('Request B');
} else {
  postman.setNextRequest(null);
}

What happens if you call postman.setNextRequest(null) in a test script?

A The collection run stops after the current request.

B The next request runs as usual.

C The current request repeats indefinitely.

D An error occurs and the run fails.

Calling postman.setNextRequest(null) stops the collection run after the current request.

Where do you place the setNextRequest() function to control request flow?

A Pre-request Script tab

B Tests tab

C Body tab

D Headers tab

You place setNextRequest() in the Tests tab to decide the next request after receiving the response.

Can setNextRequest() create loops in a Postman collection?

A No, it only moves forward.

B Only in the pre-request script.

C Only if you use external scripts.

D Yes, by setting the next request to a previous one.

You can create loops by setting the next request to a previous request using setNextRequest().

If you want to run Request C only when a variable isReady is true, what should you do?

A Use an if statement in Tests tab to call <code>postman.setNextRequest('Request C')</code> only if <code>isReady</code> is true.

B Set <code>isReady</code> in the Pre-request Script tab.

C Always call <code>postman.setNextRequest('Request C')</code>.

D You cannot control request execution based on variables.

Use an if condition in the Tests tab to call setNextRequest() only when the variable is true.

What is the default behavior if you do NOT use setNextRequest() in a collection run?

A Only the first request runs.

B Requests run randomly.

C Requests run in the order they appear in the collection.

D The collection run stops immediately.

By default, Postman runs requests in the order they are listed in the collection.

Explain how setNextRequest() can be used to control the flow of requests in a Postman collection.

Think about how you decide which request runs next after one finishes.

Describe a scenario where you would use postman.setNextRequest() to skip some requests.

Imagine you only want to continue if a test passes.
